PORTLAND, Ore. (AP) -- An Alaska Airlines passenger accused of trying to open an emergency exit during a flight from Anchorage, Alaska, to Portland, Ore., is expected to make his first court appearance Tuesday before a federal magistrate.

Alexander Michael Herrera was arrested and booked into a Portland jail Monday on a charge of interfering with a flight crew.

Witnesses say the 23-year-old Herrera tried to open the emergency exit during the plane's descent into Portland. Other passengers say they had to help restrain him using shoelaces and seat-belt extensions.

FBI spokeswoman Beth Anne Steele says passengers and crew on Flight 132 told investigators Herrera made "unusual statements" before trying to open the plane's door. She says he set off an alarm by pulling the door handle in the emergency-exit row.

Steele says Herrera is from Arizona, but she didn't know his home city.
